Take as much time as you need (even a year) and study like crazy for the LSAT. A 3.85 is a good enough GPA to get you into Harvard. Don't waste it on Tulane, or any school with abysmal job prospects for that matter.

Or, if you absolutely have your heart set on Tulane, retake and get a ton of scholarship money. Would you wait a year if it meant someone would pay you ~120k? I would think yes.
